I have doubts about the code below:
Complejo Complejo::operator+ (const Complejo &c){
Complejo resultado;
resultado.real = real + c.real;
resultado.img = img + c.img;
return resultado;
}
In this operator, what is the difference between "real" and "real"?
In the following code you are implementing the sum of the current element with another Complex and return the sum in another element, that is:
Complejo foo = ....;
Complejo foo_2 = ...;
Complejo res = foo + foo_2;
So the task is done using foo , so to access the elements of foo within the class you could use this->algun_valor or simply algun_valor , because just that differentiates real and c.real , real refers to foo and c.real refers to foo_2
